Vulkan: Exclude compute/preFrag only access images from event This further restricts VkEvent usage for certain usage patterns. If image is only used by compute, use VkEvent also will not benefit it since compute itself can not overlap with compute (assume there is only one compute engine and compute work can not overlap with each other). Similarly this also applies to KPreFragment stages. Basically after this CL, use of VkEvent is limited to usages that crosses different execution units (modeled against tiler based GPUs where there are pre-fragment stages and fragment stages and compute and all others). Before this CL, we are seeing performance regression with antutu_refinery and streets_of_rage_4 due to overhead of VkEvent, which is fixed with this CL.
